What type of chick?

I got a couple of these girls from the pullet bin at tractor supply. I assumed they were some type of red but they're first feathers are coming in white. Now I'm not do sure. Any ideas? I know it's not easy.

Maybe a Isa Brown. I have two of them. They are tanish golden and have two darker lines that go down there backs... My chicks are 4 days old.
